To many the Messiah was Jesus, born to a Virgin, and after a three year mission was crucified. He was then Resurrected, his Twelve Disciples and St Paul taking the message of his Resurrection to the known, Gentile world.
By the 4th century, the new religion of Christianity had gained a foothold in the Roman Empire, and in order to save the empire, Constantine the Great saw cohesion in the faith. He granted toleration to Christians and began a process of standardization that led to the Nicene Creed – that there is but One God and he is three, the Father, the Son and the Holy Spirit.
The empire was saved for over a hundred years, but as it collapsed, St Augustine of Hippo saved Christianity once more by declaring that it was above any earthly authority, thus allowing it to survive the collapse of Rome.
Together with other Church Fathers, St Augustine allowed Christianity to grow, in the Celtic Church in Ireland, and other areas. The pope, Gregory the Great condensed ritual into a universal, or Catholic form. Christianity was set to become the primary force of world history.
